Description
Technical field
The utility model relates to a kind of optical coupling type lever and gear wheel case, is applicable to the exercycle in the fitness equipments.
Background technique
General indoor magnetic bike, in structural design, design to exercise intensity all is by the ferrous flywheel high speed rotating, then with magnet close flywheel slowly, by the rotation that is used for suppressing flywheel of magnetic force, the distance of magnet and flywheel is near more, resistance is big more, and sporter's exercise intensity is big more, when the distance of magnet and flywheel is far away more, resistance is more little, and sporter's exercise intensity is more little; Magnet is combined by several, i.e. the magnetic control group.
In the exercycle industry, be divided into electric motor car and two kinds of control system of handcar substantially by structure.Electronic machine all generally adopts gear-box (reduction gearing mechanism) system, and handcar then is the sporter directly comes controlled motion intensity with the handling mechanical device a size.
In the prior art, when indoor magnetic control electric body building car moves, the resistance control system, see Fig. 1, comprise electronic watch (single-chip microcomputer) 1 ', gear-box 2 ', cable wire 3 ', magnetic control group 4 ', described magnetic control group 4 ' by cable wire 3 ' be connected gear-box 2 ' on, be installed in described gear-box 2 ' output shaft on variable resistor and single-chip microcomputer 1 ' be connected by winding displacement.Electronic watch 1 ' be is stored in the relevant parameter of exercycle in the software, selects to use for the user, and single-chip microcomputer is furnished with visual display and operation push-button; Gear-box 2 ' be to combine by several small gears, constitute a speed reducer, provide power by a small motor; The sense of rotation and the rotation time of display screen may command small motor; Cable wire 3 ' be common steel wire rope yarn, with gear-box 2 ' rotational travel be delivered to magnetic control group 4 ', control magnetic control group 4 ' move around within the specific limits, change magnetic control group 4 ' and flywheel 5 ' between the gap; Magnetic control group 4 ' be by several equal-sized small magnets, permutation and combination produces high magnetic fields together according to a certain order, utilize magnetic field come controlled motion flywheel 5 ' rotating speed, change magnetic field and flywheel 5 ' the gap, can change exercise intensity.Working principle is as follows: the operator operates single-chip microcomputer and comes the rotation angle of control gear case by variable resistor, and the pulling cable wire changed the gap of magnetic field and flywheel when gearbox output shaft rotated, the change exercise intensity.There is following shortcoming in actual use:
(1) because variable resistor (carbon film) itself can't satisfy accurately cutting apart of voltage, linear bad, cause The whole control system and industry standard (EN957-5-2009 motion power) widely different, i.e. actual motion performance number offset criteria design load;
(2) wire rope structure is under stressed situation, and its flexible stroke structure can change, and influences the stroke accuracy of magnetic control group, reduces the motion power level standard of exercycle;
(3) gear-box and magnetic control component body are installed, and are unfavorable for the integral body assembling and the debugging of motion power precision of ride.
Summary of the invention
The utility model will solve that existing resistance control system exists that stroke is inaccurate, the problem of complex operation, adjustment poor operability, provide a kind of stroke accurately, compact structure, the optical coupling type lever and gear wheel case being convenient to install.
The technical solution of the utility model:
Optical coupling type lever and gear wheel case, be installed in the below of exercycle flywheel, it is characterized in that: comprise fixed support, magnetic control group and gear-box are installed on the described fixed support, in the described gear-box driving gear set is installed, the driving gear of described driving gear set is connected on the motor, and an end of the output shaft of described driving gear set is equipped with the optocoupler photographic plate, on its other end eccentric wheel is installed; Be equipped with on the described magnetic control group with eccentric wheel near the Lever type support.
Further, described Lever type support abuts against with eccentric wheel by spring, and an end of described spring is connected with the Lever type support, and its other end is connected on the fixed support.
Further, the optocoupler of described optocoupler photographic plate is locked on the gear-box by screw.
The utility model is connected to single-chip microcomputer by private wire, the sporter operates single-chip microcomputer, single-chip microcomputer can be exported dependent instruction, motor obtains can rotating according to specific direction behind the voltage on the gear-box, the drive driving gear set is rotated, and rotates thereby drive output shaft, and eccentric wheel also and then rotates, this moment Lever type support and simultaneous displacement of magnetic control group reaches the purpose that magnetic control group and wind wheel gap in certain range change.
Motor speed of the present utility model utilizes gear train to reduce, and improves output shaft moment, guarantees the displacement of enough strength control magnetic control groups; Drive photographic plate when gear rotates and rotate, at this moment on optocoupler, have photosignal and export to single-chip microcomputer, the commentaries on classics of control motor--stop, realize accurately location; When eccentric wheel rotated, Lever type support and the simultaneous displacement of magnetic control group reached the purpose that magnetic control group and flywheel gap in certain range change, and this modular connection reaches the control angle and effectively transmits.
The beneficial effects of the utility model: installation and debugging are gathered, are convenient to precision height, structure essence.
